011. PUMP.

Application filed July 25, 1925. Serial No. 46,061.

To aZZ whom it may concern:

Be it known that I, JOHN R. T'RAUTNER, a citizen of the United States, residing at ted ing, in the county of Goodhue and State of Minnesota, have invented a new and useful Oil Pump, of which thefollowing is a specification.

This invention relates to improvements in oil pressure feed systems of internal combustion engines in which a positive pressure pump is employed as a part of the lubricating system.

An important object of the invention is,

to provide a pump of this character which is of a novel construction to permit the same to be readily and easily removed and replaced for inspection of the pump and oil strainer forming a parttliereof.

A further object of the invention, is to provide means for forcing the oil through the system eliminating the use of oil tubing connections, thereby further facilitating the removal of the pump.

A still further object of the invention is to provide means whereby the driving gears of the pump will be throughly oiled by the oil overflow from. the pressure relief which forms a part of the assembly.

it-h the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawings:

Figure l is an elevational view of a pump assembly constructed in accordance with the invention.

Figure 2 is aplan view of the pump oasmg.

Figure 3 is a side eievational view thereof.

Figure -1- is a sectional view taken on line i.-l of Figure 1.

Figure 5 is an elevational view of the supporting plate and bracket forming a part thereof.

Figure 6 is a sectional view taken on line 66 of Figure 4.

Figure 7 is a sectional view taken on line 77 of Figure 1.

Figure 8 is a plan view of the supporting plate.

Figure 9 is an enlarged elevational view thereof.

Figure 10 is a side elevational view of the supporting plate.

Figure 11 is a bottom plan view of the pump housing.

Referring to the drawings in detail, the reference character 5 indicates the crank casing of. a motor vehicle which is provided with a cut out portion which is closed by the removable plate 6 which is secured to the crank-casing by means of the bolts 7. This plate 6 is formed with an enlarged portion 8 that is provided with a bore 9 communicating with the bore 10 that in turn communicates with pipe 11 that forms a part of the feed system of the internal combustion engine.

Lugs 12 are provided on the inner surface of the plate 6 and are formed with threaded openings to receive the bolts 13 that secure the plate 14 to the plate 6, the plate 14 acting as a supporting plate for the pump bracket 15 and pump housing 16, formed at the lower end thereof.

Bearings indicated at 17 are formed on the pump bracket and accommodate the pump shaft 18 that carries a pump not shown on its lower end, which pump is of the usual construction and mounted in the pump housing 16. The pump housing is provided with an outlet opening 19, the outlet opening 19 being designed to receive the lower end of the tube 21 that has its upper end formed with an elbow 22 tapered to be positioned in a suitable threaded end of the bore 9.

Thus it will be seen that oil will be pumped upwardly through the tube 21 and into the bore 9, from where it passes to the bore 10 and pipe 11. The pump shaft 18 carries a pinion 22 at its upper end which pinion meshes with the pinion 23 of the shaft 24 that operates to transmit rotary movement to the shaft 18 and pump mounted at the lower end thereof.

Oil enters the pump housing 16 through the pipe 25. A screen indicated at 25 surrounds the pump housing 16 and eliminates any possibility of foreign matter contained in the oil from passing into the pump housing 16. An opening indicated at 26 is provided in the bore 9 and provides an overflow for oil when the pressure in the pipe 11 or oil system is excessive. The opening 26 is arranged directly over the pinion 22' so that oil passing through the opening will fall onto the pinion to automatically lubricate the pinion.

From the foregoing it will be seen that should it be desired to remove the pump to examine the same, or repair the elements thereof, it is only necessary to remove the bolts 7 and withdraw the entire assembly from its position within the crank casing, thereby ellminating the necessity of disconnecting pipes or tubes of the usual lubricating system.

I claim 2- 1. In a device of the character described, a supporting plate, a pump bracket formed intregral with the plate and disposed at an oblique angle with respect thereto, bearings forming a part of the bracket, a pump shaft supported within the bearings and carrying a pump element at its lower end, said bracket and pump shaft adapted to be moved bodily with the plate, and a pipe extending from the pump adjacent to the plate, to deliver fluid therethrough.

2. In a device of the character described, a supporting plate, a bracket formed integral therewith and having a pump housing at its lower end, a pump shaft mounted on the bracket and carrying a pump element at its lower end for operating within the pump housing, said plate having a bore to permit oil to pass therethrough, a pipe establishing communication between the pump housing and bore, means for rotating the pump shaft, and means for securing the plate to an engine base.

3. In a device of the character described,

a supporting plate removably secured to a crank casing, a bracket formed integral with the plate to be removed with the plate, a pump housing at one end of the bracket, a pump shaft supported by the bracket and carrying a pump element at its lower end operating in the pump housing, and means for rotating the pump shaft.

4. In a device of the character described, a supporting plate, a bracket having its upper end secured to the supporting plate, a pump housing at the lower end of the bracket, bearings forming a part of the bracket member, a shaft operating within the bearing and carrying a pump element at its lower end, said pump operating in the pump housing, a pinion carried at the upper end of the shaft, a pipe leading from the pump housing, said plate having a bore in communication with the pipe to receive fluid therefrom, said bore having an overflow disposed above the pinion, and said opening adapted to deliver fluid to the pinion.

5. In a device of the character described, a pump assembly comprising a supporting plate, a bracket formed integral with the supporting plate, said bracket including bearings, a pump shaft operating in the bearings and carrying a pump element at its lower end, a pipe for delivering fluid from the pump to the plate, and means for rotating the pump shaft.

In testimony that I claim the foregoing as my own, I have hereto affiXed my signature.

JOHN R. TRAUTNER.
